1 Claim; .(Cl. 292-263) Myinvention resides in a devicedesigned forblind stop, underlying the anchor plate, and use as a-storm sash holder,and embodies in registering with the slot 16 and the circular itsconstruction means for supporting the storm recess 17 therein.

The lock washer permits a window a ly f ypp v construothe toggle members to pivot on the bolt 26 with t in Whichthe p face Plate is indicated a yielding frictional contact. The head ofthe by e numeral 9, and t blind p by the bolt 26 is elongated so as toconstitute a crank numeral 11. The storm sash 12 has a hooked, h ndle,by means of which thetoggle may be ropivotal eehheetieh; as at betweenits upper tated about the aligned pivotal points 22 and cross ra nd theplate 0, When in its 25, when the storm sash is in its closed position.

F closed position, is adapted to lie fiat against the A spring actingexpansively is confined beblind stop. tween the headof the stud 25 andthe side of Near the lower end 0 ea O th Opposite the toggle member 24.In the drawing, I have lind t p a anchor plate 14 is permanently shown ablade spring 28, attached at one end to a at ach by means of screws 5,passed through the toggle member 24, and provided at its free rperforations in the anchor plate, and entered end with a perforationthrough which the stud into t e blind p- The anchor plate 14 is 25 ispassed; but any type of spring may be used slotted laterally from itsinner edge, as at 16, for the purpose, I and is counterbored at the endof the slot, to With the storm sash supported upon the hooks provideacircular recess 17 on its inner side, 13, the shankof the stud 25 maybe passed into ior a purpose which later will be described. 'A the slot16 by compressing the spring 28 againstchannel 18, is cut partly acrossthe face of the the anchor plate, and the head of the stud entered inthe circular recess 17. The spring 28 then acts to prevent accidentaldisengagement of the head of the stud from the recess.

The toggle member 24 is provided at its inner end with an offset finger29, which overlies the corresponding inner end of the member 23, whichfinger serves as a stop to maintain the toggle in its open position, asin Fig. 2, and prevent downward deflection. A like finger 30 is providedupon the outer end of the toggle member 24, and is adapted to extendover the corresponding outer end of the toggle member 23. In closing thestorm sash, the toggle members are caused to extend upwardly as in Fig.1, and when the storm sash is completely closed, the pivotal points 22and 25 are in axial alignment, as before stated. The toggle may then berotated as a whole by means of the projecting end of the bolt 26, andbrought into the lower position indicated in Figs. 3 and l, at whichtime, the finger 30 will lie to the outer side of the toggle member 23,so that the storm sash cannot be opened until after the toggle has beenreversely rotated to its upstanding position. This arrangement preventsthe storm sash from being opened from the outside, and securely holds itagainst rattling.

' A stay bar 31 pivoted at one end to the toggle member 23, is providedupon its under edge with one or more notches in the region of its freeend, any one of which notches is adapted to take over the finger 30,when the storm sash is opened, and to so maintain the storm sash in afixed opened position. The stay bar 31 is adapted to be folded intoparallelism between. the toggle members, when the toggle is folded, asindicated in Fig. 4, when the storm sash is closed. A stop 32,projecting over the pivoted end of the stay bar, serves to restrain thesaid bar from falling below its operative plane, as shown in Fig. 1. Thefree end of the stay bar 31 projects beyond the stop 11 and into thechannel in which the upper sash of the window moves. By lowering thissaid upper sash until its bottom rail rests upon the inwardly projectingend of the stay bar 31, the storm sash will be held securely in itspartially opened position, thus affording excellent ventilation over thelowered upper sash, and effectively excluding rain, snow, or directblasts of air. If the said upper sash be secured in its ventilatingposition, as described, the storm sash cannot be moved from the outside,with the result that entry through the window is prevented. This is adesirable assurance whenthe rooms are used at night for sleepingpurposes.

When a change of season renders the continued use of the storm sashunnecessary, the latter may be detached by simply disengaging the studs25 from the anchor plate 14., and unhooking at the connection 13. Thestorm sash may then be stored, and again be as easily replaced inposition, when the cold season approaches.

Having thus described my invention, what I claim and desire to secure byLetters Patents of the United States, is:

A storm sash lock and regulator comprising a pair of links connected toform a toggle, pivot members for connecting the opposite ends of saidtoggle to a storm sash and window frame respectively, said toggle beingswingable about the axes of said members into and out of lockingposition when the storm sash is in closed position, an element on one ofsaid links for coaction with said other link to secure said sash inclosed 1 position when said toggle is swung into said locking position,and a stay bar on said other link for coaction with said element toretain the sash in a predetermined open position.
